Summary

"This trial aims to study ways to help individuals with head and neck cancer who experience restricted jaw movement. They will conduct a small study with 30 participants undergoing radiation therapy, comparing usual care with a new

Who is the study for?
This trial is for individuals with head and neck cancer who are about to undergo radiation therapy. They should be new patients at the HNC clinic and willing to participate in a study that could involve additional physical therapy.
What is being tested?
The trial is testing whether early physical therapy can help prevent or reduce trismus (lockjaw) compared to usual care, which involves exercises and referral for physical therapy only after trismus is detected.
What are the potential side effects?
Since this intervention includes supportive care like manual therapy and jaw exercises, side effects may include discomfort or pain from the exercises, fatigue of the jaw muscles, or soreness from manual therapy.
